So 2.5cm = 25mm.

To convert cubic centimeters (cm³) to cubic millimeters (mm³), you multiply by 1,000, since there are 1,000 mm³ in 1 cm³. Therefore, to convert 25 cm³ to mm³, you calculate 25 cm³ × 1,000 mm³/cm³, which equals 25,000 mm³.
To increase 12.5 by 25 mm, you first need to convert 12.5 into the same unit, which is millimeters. Since 12.5 cm equals 125 mm, you then add 25 mm to that. Therefore, 125 mm + 25 mm equals 150 mm, which is equivalent to 15 cm.
To compare 12.5 cm and 25 mm, first convert both measurements to the same unit. Since 1 cm equals 10 mm, 12.5 cm is equivalent to 125 mm. Therefore, 12.5 cm by 25 mm represents a rectangle with dimensions of 125 mm by 25 mm.
25 cm equals 250mm...
2.5 cm = 25 mm

25 cm equals 250mm...
1 cm = 10 mm Add a zero to the centimetre figure eg 210cm = 2100mm or 25 cm = 250mm
80 cm = 800 mm
1 meter is equal to 1000 mm. 25 cm is equal to 250 mm. So 1m 25 cm is equal to 1250mm.
it 10 mm equals 1 cm then 500 mm equals 50 cm so then 580 mm equals 58 cm so the answer is 58.1 cm
1.5 cm equals 15 mm.
